Answer
Graphing online with desmos.com,
we find that the graph of the LHS
is not equal to the graph of the RHS.
The factorization is incorrect.
The correct factorization is
$2(x-2)(x+3)$

we find that the graph of the LHS
is not equal to the graph of the RHS.
The factorization is incorrect.
Factoring, extract the gcf, 2
$2(x^{2}+x-6)$
Now, search for two factors of -6, whose sum is $+1...$
,,, and find $-2$ and $+3.$
Testing the graph of $2(x-2)(x+3)$, we find that the graphs now coincide.
